CABLELAYER IS LATEST REFERENCE FOR BATTERIES

摘要

As highlighted in the December 2015 issue and in the OSJ Guide to OSV Propulsion published earlier in 2015, batteries can play a leading role and promise more efficient use of energy. In hybrid ships with energy storage in batteries, power control can be optimised, fuel cost, maintenance and emissions reduced and a vessel can be made more responsive and safer. Among the latest contracts awarded for batteries for an offshore vessel is one awarded to Saft by ABB Marine to supply a specialised high power liquid-cooled lithium-ion (Li-ion) super phosphate (SLFP) battery system for ABB's new hybrid propulsion cablelay vessel. The batteries on the cablelay ship will deliver energy while loading cable and for propulsion assistance, helping to cut the vessel's fuel consumption by 27 per cent and reducing maintenance compared with traditional AC systems. The SALT 306 CLV design vessel will be 140m in length with a beam of 30m. It is being built at Kleven shipyard in Norway. Delivery is expected in 2017.
